Actually, this is from my PC.  Standard DOS 5.0 does not seem to come with
setup or a "serctl" command.

I bought a $50 book explaining this stuff, but even the software that came
included with it found no problems with the COM1, _except_ that the port
IRQ was not enabled.  When I used the software to enable it, doing "echo
dir >com1" still failed.  And, in fact, after I checked the IRQ again, it
became disabled again!  I also looked at the motherboard pamphlet and
there do not seem to be any jumpers for the COM1 port.

My next experiment is to see if I can send _anything_ from that COM1 port
by booting up into Windows NT, connecting the COM1 port to my Linux
machine, and try the "echo dir >com1" again.

Sorry.  This problem seems very off-topic from my original problem of
trying to get LapLink working!
